No longer recommended
Contact Form DB has removed from the WordPress Plugin Directory due to a security vulnerability.
We now recommend Advanced Contact form 7 DB which we preferred in our review of a range of Save Contact Form 7 extensions.
Contact Form DB
Saves submitted form data to the WP database and provides short codes to display it.
Contact Form DB will save all your Contact Form 7 form submits to the WordPress database. It is very often used by experienced WP users to provide a record of all form submissions, even when things go a little wrong. Submission storage plugins are very robust and rarely fail to save a Contact Form 7 submit, even if the email is not sent due to a JavaScript Conflict or other email sending problem.
You can also use a range of shortcodes to display the data on your site. The plugin also includes a shortcode builder page to set shortcode options.
As a bonus, Contact Form DB now works with many other popular WordPress form plugins, so you can maintain your form submission data even if you change to another form plugin.
